Keel damage on GRP hull

[mikehhogg]

I dont think sending a tube of sikaflex on an aeroplane constitutes a hazard,I would be more worried about the lithium ion batteries in your laptop

[Matt]

Yeah, sika would be OK wouldn't it.

[mikehhogg]

it should be,there should be lots of wind generators around the Falklands and maybe the maintainance guys could lend a hand.

I've never used 7800 but the fact that it is "easy to sand" and has a "fast sanding time" would suggest it wouldn't be too resilient to a sandy / rocky beach.

Can you put out a plea on the local Facebook page for some assistance. If it's anything like the Outer Hebrides, there will be someone whose cousin has a friend that can cobble something together.

[mikehhogg]

7800 is as good as it gets for fibreglass repairs. Its the number one choice for professionals for decent permanant repairs,not cobbled jobs.Its got a fast curing time because when your hanging out of a turbine blade ,hundreds of feet in the air ,you would like a fast curing time and you do not want to climb it again the next day

More likely to get searched ... you weren't the first to think of that one


There are wind turbines here, though I don't know if there is the need or the expertise to climb them on the outside for repairs. I shall ask though

[mikehhogg]

I can try and send you a tube if you want.

[Matt]

I think the old wind turbines are all pre-peg autoclaved stuff. I don't think there's much plastic padding on them?

What a nice guy you are, that is a very kind offer.

I guess they use the Sika 7800 if the blade gets damaged by a bird strike or something. It only has to withstand air friction rather than beach friction so I'm not sure how long lasting the repair would be.

[mikehhogg]

Is there really such a thing as a permanent repair when it comes to boats and the elements. The only advantage of using this product is that it wont affect a future full repair.

Sorry to disagree but whilst 7800 might be good (and I'm sure it is, Sikaflex products usually are), "as good as it gets" for fibreglass repairs is..... fibreglass

[Matt]

Well, there certainly are upgrades from bog standard fibreglass (probably polyester resin & chopped strand) for a repair, depending on what & why the repair is required.

[Jon Tallis]

There certainly are, but they're all laminated FRP of some sort .......

[Matt]

I wonder if he can get JB Weld on the island. That's decent stuff

I’ve always struggled with the stuff. I have had several failures of adheasion, although one was stainless and another copper. it also doesn’t sand a feather edge it chips off in small craggily edges that are less than appealing if painting.

[Matt]

Interesting. I like it - it's strong. The spacers on my motor (tall deck motors need spaces to fit most manifolds) are JB welded on. The other option was tig welding, but the heat distorts the manifold. Never had a problem sanding it either - although I usually file it rather than send.

[mikehhogg]

some people are missing the point and going off on a tangent. the OP is looking for a quick decent repair to keep him going untill he can get the likes of matting and epoxies etc to his home address. He does not have the luxury that most of us have. I could have recommended one of sand and one of cement .

[Matt]

Not so much. JB Weld is a mainstream epoxy that the OP could conceivably get from a hardware store that would do a decent job in the short to medium term.

[mikehhogg]

for sure but for the price and quantities that would be used it may be cheaper to buy a boat.
